Extruder idler MMU2S

This is a redesign of the PRUSA Extruder Idler MMU2S.\r\nThe enhancement involves enlarging the pivot hole from 3.4mm to 4mm, allowing it to be lined with a 4mmx3.15mm aluminium pipe for improved stability.\r\nUsing an aluminum pipe decreases the pivot gap from 0.4 to 0.15mm, which significantly enhances FINDA (filament detector) performance.\r\nAluminum pipes can be obtained at model hobby stores.\r\nCut the tube down to 20.5mm and deburr one end for smooth integration.
